3M 7000000721 Deburring Wheel 2 in Silicon Carbide Density 2

Product Description

The 3M 7000000721 is a unitized deburring wheel designed for light material removal, surface blending, and edge finishing on metal workpieces. Built with silicon carbide abrasive at a fine, soft grade and a density rating of 2, this wheel delivers consistent, controlled cut action without aggressive stock removal. It measures 2 inches in diameter with a 1/2 inch face width and a 1/4 inch center hole. Rated to 16,100 RPM, it is suited for high-speed power tool applications. Machinists, fabricators, and tool room technicians typically install and use this wheel in production or bench finishing operations.

This deburring wheel fits a wide range of stationary and handheld power tools commonly found in metalworking and fabrication environments. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its compact 2 inch diameter makes it practical for both inline and right-angle die grinder setups where access to tight contours or part edges is required. The unitized construction holds the abrasive uniformly throughout the wheel body, maintaining consistent performance as the wheel wears down during use.

Key Features

• Silicon carbide abrasive for use on non-ferrous metals, cast iron, and hard-to-grind materials
• Density grade 2, soft: conforms to workpiece contours for consistent surface contact
• Fine grade abrasive for light deburring, edge blending, and finishing passes
• Unitized wheel construction maintains abrasive density and cut consistency throughout wheel life
• 16,100 RPM maximum speed rating supports die grinder and high-speed backstand operation
• 1/4 inch center hole fits standard die grinder mandrels without adapters

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1/4 inch arbor hole fits standard mandrels used with these tool types.

Installation Notes

Installation is typically performed by machinists or tool room technicians. Before mounting, confirm the tool spindle speed does not exceed the 16,100 RPM maximum rating marked on the wheel. Power down and disconnect or lock out the tool before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and do not use a damaged wheel.
